The trachea is the tube linking the cricoid [[Bones and Cartilage - Anatomy & Physiology#Types of Cartilage|cartilage]] of the [[Larynx - Anatomy & Physiology |larynx]] to the [[Bronchi and bronchioles - Anatomy & Physiology|bronchi]], forming part of the conducting system which transports air from the external environment to the [[Lungs - Anatomy & Physiology|lungs]]. The [[Oesophagus - Anatomy & Physiology|oesophagus]] lies dorsally to the trachea.

The cervical part of the trachea lies generally in the median position, although this varies slightly depending on the position of the head.

The thoracic part of the trachea crosses the aortic arch, thus it's positioning is moved slightly to the right at this level.
